Dam Project Concept in Timor Leste

1. Project Concept The “Project Concept” should include the following items Project Concept 1. Project Name 2. What is the Project outline? 3. Where is the Project located? 4. What is the scale of the Project? 5. Why the Project is expected/initiated? 6. How much is the rough cost estimate of the Project? 7. When the Project should be completed? 8. What are the Project benefits? 9. How to get the budget for O&M? 10. What are specific issues to be studied? 11. What is the budget source? 12. How much is the rough cost of FS, if FS is necessary?

2. 1. Project Name Construction of multi-Purpose dam in Sui 2. Outline of Project Dam Construction and Irrigation Channel Improvement Water supply canal Construction to Tasi -Mane Projects Raw Water Supply Through Water Purification Plant Increasing Water Supply to Irrigation Area (2500 ha) During Dry Season Industrial development Dam Body

3. Project Location Map or Photo Sui, the lower reaches of the Caraulun river on the south coast of the TL

4. Dam Site = Sui ( Caraulun ) Location = 8,2 Km northeast of same village Irrigation Area = 1150 ha(current) Expected develop to = 2500 ha Reservoir Volume = 35 mil m3 (Expected) Dam Height = 50 m and Weight = 500 m (Expected to construct) Access Road = 9 km Calculation Water of Supply and Demand Rainfall (mm) = 2484 mm/year Catchment area = 129 km ² Water Available in dry Season = 1.4 mil m ³ /month Required water for irrigation = 29.2 mil m3/3month (Dry Season) for 2500 ha Land Water Shortage (Dry Season) = 25 mil m3/3months for 2500 ha paddy land Required water for 50.000 People = 0.18 mil m3/3months Required water for 4000 animals = 7200 m3/3months 4. Project Scale Inundation area Dam Body

5. 5. Rough Cost estimate Sui Dam There are many variables that can influence the Cost of construction in the Dam, therefore there are some study should Conducted such as: Analyze Type of Dam (Rock Fill, Earth Fill, or Concrete gravity Dam) Availability of Near Material to Construct the Dam (Quarry) (Can reduce Construction Cost) Analyze Mobilization of Equipment and material (Overseas Company and Exporting Material such as Steel and other Material) local Material which can utilized to construct the Dam (can reduce the cost) Inundation Area measure (related to reservoir capacity) Constructions Method that use (where Sui only have 3 months of dry season)

6. 6. Timeline of Implementation The timeline implementation of the project is presented in the following table. FS DED Land Construction O & M 2024 -2025 2025-2026 2027 2027 - 2030 2030 9 m 10 m 12 m 4 years

7. 7. Project Benefits Note: Paddy cost production is $ 0.4/kg according to MAF Farmers Socio Economic Survey. Beside the direct financial benefit, intangible benefits: Improve productivity of people (Improve public health and sanitation Improve the existing environment into green zone. Enhance sustainability of groundwater system (water in the DAM shall penetrate ground surface and recharge the aquifer) Enhance other sectors such as tourism, water sport activity, fisheries, hotel, business, etc.

8. 8. Financial prospect for O&M Sedimentation Removal Cost will be detailed calculated by Consultant where it’s covers from method of removal and cost of removal. No Product Budged Allocation for O&M A Annual Revenue ( Usd ) $22,860,000 B Expenditure for O&M ( Usd ) =(3% X A) $685,800 DETAIL ANALYSIS C Staff number for O&M = 12 People x $400/month $57,600.00 D Maintenance of Irrigation Canal /years $150,000.00 E Sedimentation Removal/years $478,200 TOTAL BUDGET ALOCATION FOR O&M $685,800.00

9. 9. Specific Item to be studied (if F/S is necessary) Type of Dam (Cost, method of Constructions) Hydrological Study: Analyzing rainfall patterns and river flow in the area to determine the expected water volume and other hydrological characteristics Topographic Study: Measuring and analyzing the topography of the surrounding area to determine the relevant land elevations and slopes for the dam design Geotechnical Study: Assessing the soil and rock conditions at the project site to determine the stability and appropriate bearing capacity for the foundation and dam structure Hydraulic Study: Examining the flow capacity and the dam's ability to control water discharge, as well as flood risk Industrial development study and mapping Economic Impact Study Sedimentation Study (analysis and Countermeasure)

10. 10. Project Source Of Budget   “Infrastructure Fund” or “Loan” or “Grant” 11. Rough Cost of Feasibility Study Very rough estimate US$2,000,000-/ per one river
